IntroductionTreatment for tuberculosis (TB) is highly effective if taken according to prescribed schedules. However, many people have difficulty adhering to treatment which can lead to poorer clinical outcomes, the development of drug resistance, increased duration of infectivity and consequent onward transmission of infection. A range of approaches are available to support adherence but in order to target these effectively a better understanding of the predictors of poor adherence is needed. This review aims to highlight the personal, sociocultural and structural factors that may lead to poor adherence in high-income and middle-income settings.Methods and analysisSeven electronic databases, Medline, EMBASE, CINAHL, PsycInfo, The Cochrane Library, Scopus and Web of Science, will be searched for relevant articles using a prespecified search strategy. Observational studies will be targeted to explore factors that influence adherence to treatment in individuals diagnosed with TB. Screening title and abstract followed by full-text screening and critical appraisal will be conducted by two researchers. Data will be extracted using the Population, Exposure, Comparator, Outcomes, Study characteristics framework. For cross-study assessment of strength of evidence for particular risk factors affecting adherence we will use the Grading of Recommendations, Assessment, Development and Evaluation tool modified for prognostic studies. A narrative synthesis of the studies will be compiled. A meta-analysis will be considered if there are sufficient numbers of studies that are homogenous in study design, population and outcomes.DisseminationA draft conceptual framework will be identified that (A) identifies key barriers to adherence at each contextual level (eg, personal, sociocultural, health systems) and (B) maps the relationships, pathways and mechanisms of effect between these factors and adherence outcomes for people with TB. The draft conceptual framework will guide targeting of adherence interventions and further research.PROSPERO registration numberCRD42017061049.

Abstract Background Seroprevalence of SARS Cov-2 provides a good indication of the extent of exposure and spread in the population, as well as those likely to benefit from a vaccine candidate. To date, there is no published or ongoing systematic review on the seroprevalence of COVID-19 in Low- and Middle-Income Countries (LMICs). This systematic review and meta-analysis will estimate SARS Cov-2 seroprevalence and the risk factors for SARS Cov-2 infection in LMICs.Methods We will search PubMed, EMBASE, WHO COVID-19 Global research database, Google Scholar, the African Journals Online, LILAC, HINARI, medRxiv, bioRxiv and Cochrane Library for potentially useful studies on seroprevalence of COVID-19 in LMICs from December 2019 to December 2020 without language restriction. Two authors will independently screen all the articles, select studies based on pre-specified eligibility criteria and extract data using a pre-tested data extraction form. Any disagreements will be resolved through discussion between the authors. The pooled seroprevalence of SARS CoV-2 for people from LMICs will be calculated. Random effects model will be used in case of substantial heterogeneity in the included studies, otherwise fixed-effect model will be used. A planned subgroup, sensitivity and meta-regression analyses will be performed. For comparative studies, the analyses will be performed using Review Manager v 5.4; otherwise, STATA 16 will be used. All effect estimates will be presented with their confidence intervals.Discussion The study will explore and systematically review empirical evidence on SARS Cov-2 seroprevalence in LMICs, and to assess the risk factors for SARS Cov-2 infection in Low Middle Income Countries in the context of rolling out vaccines in these countries. Finally, explore risk classifications to help with the rolling out of vaccines in LMICs.Systematic review registration: The protocol for this review has been registered in PROSPERO (CRD422020221548).

BackgroundPersonality disorders are now internationally recognised as a mental health priority. Nevertheless, there are no systematic reviews examining the global prevalence of personality disorders.AimsTo calculate the worldwide prevalence of personality disorders and examine whether rates vary between high-income countries and low- and middle-income countries (LMICs).MethodWe systematically searched PsycINFO, MEDLINE, EMBASE and PubMed from January 1980 to May 2018 to identify articles reporting personality disorder prevalence rates in community populations (PROSPERO registration number: CRD42017065094).ResultsA total of 46 studies (from 21 different countries spanning 6 continents) satisfied inclusion criteria. The worldwide pooled prevalence of any personality disorder was 7.8% (95% CI 6.1–9.5). Rates were greater in high-income countries (9.6%, 95% CI 7.9–11.3%) compared with LMICs (4.3%, 95% CI 2.6–6.1%). In univariate meta-regressions, significant heterogeneity was partly attributable to study design (two-stage v. one-stage assessment), county income (high-income countries v. LMICs) and interview administration (clinician v. trained graduate). In multiple meta-regression analysis, study design remained a significant predictor of heterogeneity. Global rates of cluster A, B and C personality disorders were 3.8% (95% CI 3.2, 4.4%), 2.8% (1.6, 3.7%) and 5.0% (4.2, 5.9%).ConclusionsPersonality disorders are prevalent globally. Nevertheless, pooled prevalence rates should be interpreted with caution due to high levels of heterogeneity. More large-scale studies with standardised methodologies are now needed to increase our understanding of population needs and regional variations.

BackgroundDespite advances in vaccination and case management, pneumonia remains the single largest contributor to early child mortality worldwide. Zinc has immune-enhancing properties, but its role in adjunctive treatment of pneumonia in low-income and middle-income countries (LMICs) is controversial and research still active.MethodsSystematic review and meta-analysis of randomised controlled trials of zinc and placebo in pneumonia in children aged 2 to 60 months in LMICs. Databases included MEDLINE, the Cochrane Library, EMBASE, LILACS, SciELO, the WHO portal, Scopus, Google Scholar and ClinicalTrials.gov. Inclusion criteria included accepted signs of pneumonia and clear measure of outcome. Risk of bias was independently assessed by two authors. ORs with 95% CI were used for calculating the pooled estimate of dichotomous outcomes including treatment failure and mortality. Time to recovery was expressed as HRs. Sensitivity analyses considering risk of bias and subgroup analyses for pneumonia severity were performed.ResultsWe identified 11 trials published between 2004 and 2019 fulfilling the a priori defined criteria, 7 from South Asia and 3 from Africa and 1 from South America. Proportional treatment failure was comparable in both zinc and placebo groups when analysed for all patients (OR 0.95 (95% CI 0.80 to 1.14)) and only for those with severe pneumonia (OR 0.93 (95% CI 0.75 to 1.14)). No difference was seen in mortality between zinc and placebo groups (OR 0.64 (95% CI 0.31 to 1.31)). Time to recovery from severe pneumonia did not differ between the treatment and control groups for patients with severe pneumonia (HR 1.01 (95% CI 0.89 to 1.14)). Removal of four studies with high risk of bias made no difference to the conclusions.ConclusionThere is no evidence that adjunctive zinc treatment improves recovery from pneumonia in children in LMICs.Trial registration numberCRD42019141602.

Abstract Background Early provision of palliative care, at least 3–4 months before death, can improve patient quality of life and reduce burdensome treatments and financial costs. However, there is wide variation in the duration of palliative care received before death reported across the research literature. This study aims to determine the duration of time from initiation of palliative care to death for adults receiving palliative care across the international literature. Methods We conducted a systematic review and meta-analysis that was registered with PROSPERO (CRD42018094718). Six databases were searched for articles published between Jan 1, 2013, and Dec 31, 2018: MEDLINE, Embase, CINAHL, Global Health, Web of Science and The Cochrane Library, as well undertaking citation list searches. Following PRISMA guidelines, articles were screened using inclusion (any study design reporting duration from initiation to death in adults palliative care services) and exclusion (paediatric/non-English language studies, trials influencing the timing of palliative care) criteria. Quality appraisal was completed using Hawker’s criteria and the main outcome was the duration of palliative care (median/mean days from initiation to death). Results One hundred sixty-nine studies from 23 countries were included, involving 11,996,479 patients. Prior to death, the median duration from initiation of palliative care to death was 18.9 days (IQR 0.1), weighted by the number of participants. Significant differences between duration were found by disease type (15 days for cancer vs 6 days for non-cancer conditions), service type (19 days for specialist palliative care unit, 20 days for community/home care, and 6 days for general hospital ward) and development index of countries (18.91 days for very high development vs 34 days for all other levels of development). Forty-three per cent of studies were rated as ‘good’ quality. Limitations include a preponderance of data from high-income countries, with unclear implications for low- and middle-income countries. Conclusions Duration of palliative care is much shorter than the 3–4 months of input by a multidisciplinary team necessary in order for the full benefits of palliative care to be realised. Furthermore, the findings highlight inequity in access across patient, service and country characteristics. We welcome more consistent terminology and methodology in the assessment of duration of palliative care from all countries, alongside increased reporting from less-developed settings, to inform benchmarking, service evaluation and quality improvement.

The Impact

Background: Breast cancer is the most common cancer in Malaysia and it is anticipated that incidence will increase by 49% from 2012 to 2025. Unfortunately, survival remains poor because of late presentation and poor adherence to evidence-based medicine. Barriers to early presentation include inadequate knowledge about the disease, financial issues, negative influence of relatives and perceived poor quality of care and services in state-run hospitals. Poor adherence to treatment is also a common struggle, and is further exacerbated by the use of traditional, alternative healing methods. While patient navigation (PN) programs have been shown to improve breast cancer outcomes in the US, its implementation and performance in low and middle income countries is not well studied. Aim: We sought to determine the impact of a PN program in reducing treatment delays and improving adherence to treatment and patient satisfaction, as well as to evaluate the barriers faced by women seeking breast cancer care in Malaysia. Methods: We established a nurse-led patient navigation center at a secondary government hospital in Klang. This clinical team involved the surgery, pathology, radiology and nursing departments and provided patient-centered care, including patient tracking and call reminder systems, family counseling, health education and decision aids. The community team involved a Patient Navigator Program Coordinator and a Community Navigator. We compared treatment delays and adherence to treatment between navigated patients and patients registered in the year prior to the PN program. We used Student t-tests and Pearson χ2 or Fisher's Exact tests to compare timeliness between navigated patients and patients registered in the year prior. Results: Of the 136 Malaysian women enrolled in the PNP in 2015, 48.9% were diagnosed with advanced disease (stage 3 or 4). Women with advance disease had a lower median monthly household income compared with women with early disease (USD $350 vs $540, P = 0.023). Women with advance disease were also less likely to have personal transportation to the hospital (36.4% vs 56.5%, P = 0.048). Compared with the year before PN, more navigated patients underwent mammography within 7 days of their first visit (96.4% vs 74.4%, P < 0.001) and received their diagnosis within 14 days of their first visit (80.0% vs 58.5%, P < 0.001). The proportion of women who met timeliness to treatment initiation was similar for navigated patients and patients in the year prior. The proportion of defaulters were marginally lesser among navigated patients compared with the year prior (4.4% vs 11.5%, P = 0.048). Conclusion: We found that integrating PN within a breast clinic of a middle income country is feasible, and in the long run, could improve outcomes for breast cancer patients. Long-term follow-up is needed to assess the impact of the PN program on improving treatment completion and survival.

Abstract BackgroundIncome level is an important factor that influences the occurrence of gestational diabetes. Thus, this systematic review and network meta-analysis aimed at evaluating the correlation between income levels and the prevalence of gestational diabetes. MethodsRelevant published studies were searched in Pubmed, Web of Science, Cochrane library, and Ovid from the establishment time of database to January 3, 2020. Finally, 13 eligible clinical studies involving 1,817,801 women were selected from a total of 3776 studies and included in this study. The statistical softwares Revman5.3 and Stata14.0 were used to compare the prevalence of gestational diabetes in five different income levels; low, lower middle, medium, upper middle, and high. ResultsThe incidences of gestational diabetes in people with different economic income levels were: high income <middle income <upper middle income <lower middle income <low income. ConclusionThere is no linear correlation between income levels and incidences of gestational diabetes. However, the overall prevalence of gestational diabetes is inversely proportional to income level, that is, the higher the income level, the lower the prevalence of gestational diabetes.

Newcastle Ottawa Scale

Background: With ageing world populations, multimorbidity (presence of two or more chronic diseases in the same individual) becomes a major concern in public health. Although multimorbidity is associated with age, its prevalence varies. This systematic review aimed to summarise and meta-analyse the prevalence of multimorbidity in high, low- and middle-income countries (HICs and LMICs). Methods: Studies were identified by searching electronic databases (Medline, Embase, PsycINFO, Global Health, Web of Science and Cochrane Library). The term ‘multimorbidity’ and its various spellings were used, alongside ‘prevalence’ or ‘epidemiology’. Quality assessment employed the Newcastle-Ottawa scale. Overall and stratified analyses according to multimorbidity operational definitions, HICs/LMICs status, gender and age were performed. A random-effects model for meta-analysis was used. Results: Seventy community-based studies (conducted in 18 HICs and 31 LMICs) were included in the final sample. Sample sizes ranged from 264 to 162,464. The overall pooled prevalence of multimorbidity was 33.1% (95% confidence interval (CI): 30.0–36.3%). There was a considerable difference in the pooled estimates between HICs and LMICs, with prevalence being 37.9% (95% CI: 32.5–43.4%) and 29.7% (26.4–33.0%), respectively. Heterogeneity across studies was high for both overall and stratified analyses ( I 2 > 99%). A sensitivity analysis showed that none of the reviewed studies skewed the overall pooled estimates. Conclusion: A large proportion of the global population, especially those aged 65+, is affected by multimorbidity. To allow accurate estimations of disease burden, and effective disease management and resources distribution, a standardised operationalisation of multimorbidity is needed.

Abstract Background Obstructed labor accounted for 22% of obstetrical complications and 9% of all maternal deaths in low- and middle-income countries. Even though there are separate studies regarding obstructed labor and its complication in Ethiopia, their results are inconsistent. The objectives of this review will be to estimate the pooled the prevalence of obstructed labor and to identify adverse feto-maternal outcomes associated with obstructed labor in Ethiopia. Methods Preferred Reporting Items for Systematic Reviews and Meta-Analyses guideline will be followed to conduct this systematic review and meta-analysis. The databases we will search will be PubMed, Cochrane Library, Google Scholar, CINAHL, African Journals Online, Dimensions, and Summon per country online databases. To search the relevant literature, we will use the following key search terms: “prevalence,” “adverse outcome,” “obstructed labour,” “maternal near miss,” “neonatal near miss,” “perinatal outcome,” “cesarean section,” “obstetric fistula,” “uterine rupture,” and “Ethiopia.” Joanna Briggs Institute Meta-Analysis of Statistics Assessment and Review Instrument will be used for evaluating the quality of the studies. Appropriate statistical tests will be conducted to quantify the between studies heterogeneity and for the assessment of publication bias. We will check individual study influence analysis and also do subgroup analysis. The STATA version 15 will be used for statistical analysis. Discussion Our systematic review and meta-analysis will provide the pooled prevalence of obstructed labor and its association with adverse feto-maternal outcomes in Ethiopia. The finding of this study will be helpful to design appropriate preventive and promotive strategies for reducing of obstructed labor-related maternal mortality.
